So although Im not concerened with the surface being centered, I should adjust to be close but in the end, I will use the programmer to set the final position correct ? Also this is before any programming is done to the servo and everything on the TX is at zero ?
Yes, yes and set the trims to neutral and end points to somewhere around 130%
At this point, I am measuring the servo arm movement on the protractor..not the actual surface right ?
Yep
AH HA!! that was the part that was not making sense to me! Im thinking the arm has to be 90 deg to the servo at all times..
The main reason why you seem to be reseting the surface travel is because as soon as you reset the center on the programmer, the end points are lost and must be reset.
Once you do it the first time it will all become clear.
It also works for multiple servos on the same surface. It takes a bit of work but you are treated to a very well flying plane
